Detailed Explanation of Key Techniques for High-Yield Garlic Cultivation
Although the garlic market was very poor in 2018, it still could not stop many farmers from choosing to plant garlic. In their words, although the market was not good this year, if they caught a good year, they would recover the losses they had suffered before. For friends who still chose to plant garlic this year, all Tuliu.com can do here is offer a little advice on high-yield garlic cultivation techniques, so as to help everyone achieve a high yield and a bumper harvest next year as much as possible.
For garlic, the growth period is basically around 220-280 days, and there is also a folk saying that “the poor do not plant garlic”, meaning that if you are unwilling to invest, then do not plant garlic. Garlic has an underdeveloped root system and a shallow root layer, and is relatively sensitive to soil water and fertilizer. If you want a high yield, you must provide enough fertilizer!
I. Land preparation and fertilization
Garlic cultivation still follows the approach of mainly using base fertilizer and supplementing with topdressing. At present, long-acting fertilizers on the market are still relatively lacking, and for a shallow-rooted crop like garlic, no matter how much chemical fertilizer is used, it is difficult to bring fertilizer efficiency into full play.
Therefore, at the stage of land preparation and fertilization, Kexue Xingnong suggests choosing a plan of farmyard manure (organic fertilizer) combined with slow-release compound fertilizer. For ordinary chemical fertilizers, nutrients are released too quickly to give full play to fertilizer efficiency. For garlic cultivation, excessive deep plowing is possible, but unnecessary. Because garlic roots are shallow and thin, there is no need for deep plowing
Regarding organic fertilizer, Kexue Xingnong reminds everyone that many friends choose undecomposed chicken manure or pig manure as fertilizer, resulting in an outbreak of underground pests the next year, especially root maggots, so special attention must be paid to this point.
II. Topdressing
The growth period of garlic is very long, and its root system is also shallow and thin. Therefore, after spring begins, the base fertilizer in the land where garlic is planted has been mostly used up. Timely topdressing is the only way to ensure robust plant growth. Topdressing should be mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. Of course, if compound fertilizer is chosen, the effect may be better. Foliar spraying can be used to promote absorption and improve garlic quality.
1. Topdressing at the garlic bolt stage
Generally in March and April it is also relatively dry. At this time, garlic is about to bolt, and its demand for nutrients, water, and fertilizer is relatively large, so garlic also needs watering. At this time, topdressing can be applied together with watering. The first watering after garlic turns green should not be done too early, otherwise during a late spring cold spell, freezing damage may occur, causing a reduction in garlic yield. When topdressing, humic acid water-soluble fertilizer can be chosen to improve fertilizer efficiency.
2. Fertilization during the garlic bulb expansion stage
At this time, the nutrient supply of garlic is mainly transported to the underground bulbs to promote bulb expansion. This period is also the key period for high garlic yield, and water and fertilizer management is especially important. Since garlic likes sulfur and at this time has a high demand for potassium fertilizer, it is recommended to apply Linsa UN potassium dihydrogen phosphate, which can not only improve garlic quality but also increase garlic yield. Of course, phosphorus fertilizer is also very necessary. At present, there are also water-soluble phosphorus fertilizers on the market, which can be applied by foliar spraying to improve fertilizer efficiency.
The above is a bit of fertilization technology introduced to everyone by the editor of Tuliu.com. We hope it is helpful to everyone, and we hope garlic can get a good price next year and achieve a bumper harvest.
